【期刊论文】Optical Salinity Sensor System Based on Fiber-Optic Array

The refractive index of salt water changes corresponding to the variation of salinity. Based on a differential refractometer, the salinity canbe measured due to beam deviation, and the influence of temperature on the measurement results is reduced effectively. Beam deviation caused by salinity change is detected by a fiber-optic array and recorded by a charge-coupled device. According to the Gauss distribution theory, the light-spot center can be determined by fitting a Gauss curve using each received light spot intensity and the position of each receiving fiber. With this method, measurement errors caused by light power fluctuation and ambient light disturbance can be avoided effectively. Variation in transmission power loss of each receiving fiber reduces the measurement accuracy of salinity. Therefore, a method of correction for each fiber transmission power loss in the array can effectively improve the salinity measurement accuracy. Experimental results indicate the feasibility of the developed system, and the measurement repeatability error is better than ±0.25‰.

【期刊论文】New mechanisms of slow light and their applications

The last decade has been of great significance for the development of slow light technology. Electromagnetically induced transparency (EIT), coherent population oscillation (CPO), stimulated Brillouin scattering (SBS), stimulated Raman scattering (SRS), soliton collision, and photonic crystal waveguides have been used to slow down the velocity of light. In this paper, some important theoretical and technical developments of slow light technology that occurred over the last decade are discussed. Novel technologies for slowing down the velocity of light and their primary applications are introduced in detail. In addition, the future developing trends of slow light and its potential applications, especially in optical fiber sensors, are also forecasted and proposed in this paper.

【期刊论文】A Novel Double-Arched-Beam-Based Fiber Bragg Grating Sensor for Displacement Measurement
赵勇, Yong Zhao, Hua-wei Zhao, Xin-yuan Zhang, Qing-yao Meng, and Bo Yuan
IEEE PHOTONICS TECHNOLOGY LETTERS 15(2008)1296-1231,-0001,():
-1年11月30日
A double-arched-beam-based fiber Bragg grating (FBG) sensor for displacement measurement is presented. Unlike most FBG sensors that measure the resonance wavelength shifts to detect the measurand, this kind of FBG sensor is proposed to measure the displacement based on the demodulation of the FBG's reflective spectra bandwidth. According to the strain distribution on the novel double-arched beam surface, the positive and negative strain will act on only one FBG, which is stuck on the beam surface. Thus, the positive and negative strain will make the spectra broaden as the displacement increases. What is more, the problem of cross-sensitivity in the FBG sensor is solved because temperature only affects the wavelength shift, but not the spectra bandwidth. Simulation and preliminary experimental results indicate the feasibility of the proposed idea and a fairly good linearity of the measurement characteristic.

【期刊论文】Novel current measurement method based on fiber Bragg grating sensor technology

Experimental setup for current measurement and a novel signal detection method for demodulation of fiber Bragg grating wavelength shift are developed. Being attached respectively on the upper and lower surface of a pendulum-type cantilever element, only a couple of matched FBGs are used for both current sensing and wavelength shift signal demodulating. So, the received light power will change due to the split of the two reflected spectrum of FBGs, which is corresponding to the electromagnetic force caused by the measured current. In addition, cross-sensitivity effect of FBG-based sensor automatically solved due to a differential signal process method. Static and quasistatic measurement results indicate the feasibility of the developed sensor system. Measurement error of

【期刊论文】Novel target type flowmeter based on a differential fiber Bragg grating sensor
赵勇, Yong Zhao*, Kun Chen, Jian Yang
Measurement 38(2005)230-235,-0001,():
-1年11月30日
A novel target type flow sensor has been proposed for liquid flow measurement in pipeline. The force created by the fluid on the target results in the distortion of a cantilever structure. A couple of fiber Bragg gratings (FBGs) are mounted at either side of the cantilever. By monitoring the wavelength shift difference of the two FBGs, the fluid flow-rate can be obtained and the cross-sensitive problem of the FBG sensor can be solved by compensating the temperature effect. Measurement theory has been described. Simulation and preliminary experiments have been carried out, and the results verify the feasibility of the proposed sensor with a measurement range from 0 to 1000 cm3/s.

High-pressure measurement is made by demodulating Bragg grating peak splitting caused by transverse stress differences in the core of a high-birefringence (HB) single-mode fiber, which is bonded on the exterior surface of a free active element bulk modulus. The two orthogonally polarized signals reflected from the HB fiber Bragg grating (FBG) can be independently detected with a simple FBG interrogation system, which is based on the light intensity measurement method. In addition, the cross-sensitivity of the FBG sensor can be self-compensated by this method. The measurement principle is introduced, and preliminary experimental results indicate that the measurement sensitivity is estimated to be~12 pm/N in a linear measurement range from 0 to 120 N.

Based on near-infrared spectral absorption and fiber-optic sensor technology, an experimental setup for low-water-content measurement of crude oil is developed. The advantages of this method include fast measurement, high accuracy, keeping the measured oil free of pollution, and being suitable for long-term on-line continuous monitoring. This technology can be used for those applications that require high-quality water-in-oil measurement and process control. The measurement resolution for water content is better than 0.005% in the range from zero to 2% by volume. Measurement errors are estimated to be

【期刊论文】Discrimination methods and demodulation techniques for fiber Bragg grating sensors
赵勇, Yong Zhao*, Yanbiao Liao
Optics and lasers in Engineering 41(2004)1-18,-0001,():
-1年11月30日
Fiber Bragg grating (FBG) sensors are one of the most exciting developments in the fields of fiber-optic sensors in recent years. One of the problems in using grating sensors is the discrimination of temperature and strain responses (cross-sensitivity effect between temperature and strain), because in most real-world applications both of these quantities will be acting on the sensor elements. Another problem is how to measure a small Bragg wavelength shift accurately. This article presents a comprehensive and systematic overview of discrimination measurement methods and demodulation techniques for FBG sensors. It is anticipated that FBG sensors will be commercialized and widely applied in practice in the near future due to the maturity of economical production of FBGs and the availability of cost effective measurement and demodulation techniques. Recent research work about a differential FBG sensor for simultaneous measurement of down-hole high pressure and temperature and the corresponding demodulation techniques are also introduced in this paper.
